What upgrades can be made to get better MPG? Air intake? Or what?

This topic has been brought up literally hundreds of times on both this and the 350z forum

Premium Mandatory?

370z requires premium fuel?

If you use a lower octane fuel you will not be getting the performance gains of running a higher octane but your engine won't blow up, it will however develop a knock

If you know anything about performance motors you want to run the highest Octane you can afford, not the lowest...
